It took me a little while (2 weeks) to really get the hang of using the peg, but once I did I found it very easy to use. I had to use a pump at first because my stomach couldn't tolerate much at one time, but after a week of that, I could do the gravity feeds. I have been doing that now for 1 month and I am two weeks out of treatment on Wednesday. I suspect I will have it for 2 more weeks and then it will be gone. It is very useful, expecially as Danny said to use with pain medication. Just make sure not to crush any tablets that are time-release for the tube, since they won't work the way they are supposed to.
Good luck,
Sarah
